Folder with a side hinge
The folder has only one side substantially connected using a side hinge. Prior art style folder front and back panels (40 and 41) are hingedly attached along a horizontal bottom edge (47). The front and back panels each have a left-hand side edge (43 and 45). These LHS edges are substantially vertical and perpendicular to the panels' bottom edge. The proximal edges (53 and 55) of side hinge (50) are hingedly attached to respective LHS edges of the panels. The hinge portions' distal edges (56 and 54) are hingedly attached together (along vertical line 60). The hinge substantially connects the LHS front panel edge to the LHS back panel edge. The lower edge of the hinge (23) is at least 1.5″ up from the folder's bottom edge (47). The hinge is short (like ¾″). The hinge folds inside/between the folder panels (like 1″ in and 1″ out).

BACKGROUND OF INVENTIONThis invention relates to file folders or file envelopes or, more specifically, expandable file folders. Heretofore, folders up till now have been mostly of five basic types: standard single-fold folders, hanging folders, jackets, pockets, expanding pocket folders, and combinations thereof.
Prior Art
Hanging folders have problems and limited uses. They are only useful in a file drawer or special rack. Papers slip out the sides even more easily than standard file folders. This is because both front and back panel top edges are supported on the rack and panels do not lie against each other. (That is, the compression of the papers against each other, that is utilized to keep standard folders closed, is not in play.) Any papers that stick out the edges of a hanging file can get bent/torn (while pulling a folder out) by the metal edge supports of the file rack. This can be most displeasing to have important papers mangled by the supporting rack. The metal hanging strips, fixed to each panel top edge, are heavy an easily droop one side of the folder open if the folder is held. The metal hangers are aesthetically displeasing to be viewed (like for a presentation). Also, front and back portions of a hanging folder are nearly indistinguishable, but for an added top tag. One must often feel down to the bottom of the file drawer to be sure one has both front and back panels of the same folder.
Pockets (3 sides closed) have many disadvantages. Prior art, like that in U.S. Pat. No. 2,330,402 by M. Winokar, granted Sep. 28, 1943, entitled MULTIPLE FILING POCKET, has an example of a pocket (shown in his
With pockets, papers (which are flimsy) must be agilely guided straight down between the pocket sides. Papers may catch on the corners, like if they are tilted. To insert papers, one often curve-stiffens papers (with one's thumb press-curving the papers against ones fingertips). The pocket is often held open with the opposing hand, and the leading edge of the papers is guided between the pocket sides. This procedure can be time consuming and frustrating, especially, as is usual, many papers must be filed.
Jackets (2 sides closed) have the tight corner problem also. The fuller the jacket the farther sideways papers extend, making jackets not so useful in the sideways-limited space of a file drawer. Vikings® Office Products Discount Buyers Guide, Spring 1999, P. 84, item A shows a jacket with tabs for indica on the side (not a design for file drawers).
Expansion pockets have other disadvantages. Guiding papers in to these pleated expandable folders requires nearly the same agile guiding-them-in that pockets require. It can be easier to guide papers in expandable folders than pockets because the size of the opening is essentially larger (because it is front-to-back deeper). The expansion pocket will fit into a file drawer. But they are bulky (deep) even when empty. They need to be fully expanded to insert papers. Also they require multiple steps of construction, which increases production costs. Winokar's Multiple Filing Pocket
Multi-pocket pleat-sided folders, (like Rupf's and Winokar's (and those with tall pleated sides) have other disadvantages. They are bulky. Pleats are also pre-formed on the bottom of each folder pocket. The whole multi-pocket unit generally must be expanded in full to place papers in any pocket. Since it is already difficult to get papers in a pocket, the bulky multi-pocket unit may have to be pulled from the file drawer and placed somewhere, like on a desk. As each pocket may be filled at different times, (like filed by month) the unit may have to sit on a desk forever to be useful. Full or not fully expanded pockets have one more glitch. A person often expands each pocket from the top, creating a more V-shaped pocket than a U-shaped one. Papers are often shoved in—all the way to the bottom—so they don't stick out the top. But because of the pocket's bottom W shape, papers can end up being crumpled (or papers already inside get smashed).

1. Description of One Embodiment of the Invention
The vertical distance between front hinge portion's upper edge 84 and lower edge 23 can be substantially ¾″. The vertical distance between back hinge portion's upper edge and lower edge can be substantially the same as the vertical distance between front hinge portion's upper edge and lower edge.
The narrower the hinge (horizontal distance between the hinge portions' edges), the more stress is placed on the hinge when opening the folder. The wider the hinge, the more confined a folder must be in a backwards tilted tray to keep front panel next to back panel.
The folder embodiments described above (
2. Description of other Embodiments of the Invention
A folder's depth (front panel to back panel) is limited when a folder's sides are confined by my side hinge or prior art pleats. Expansion of the bottom of a folder can have issues.
With prior art pleated pocket folders, the bottom W can't naturally spread open much because of the restrictive sides. If such a pocket is not fully expanded, top to bottom, even the side pleats can pinch-grab papers as they are inserted.

3. Common Specifications of the Invention
Common specifications are also described in the embodiments discussed. Prior art folder panels, and embodiment panels, are of a size and shape, when hingedly attached, to contain papers. Height/width dimensions of folder panels can be, but are not limited to being ≈9″×12″ (8 ¾″ one panel, often minus tab cut-out, 9″ other panel, often plus ½″ tab) for 8.5″×11″ letter papers. Width of legal folders is ≈14⅝″ for legal 8.5″×14″ papers, other dimensions being similar to letter. Dimensions may be of a prior art size and shape to contain A4, B5, A5, Executive, half letter, index cards, envelopes, photographs, Panoramic, and other size papers and sheet materials. All dimensions have been listed in inches, but all approximate to centimeters (1 cm. ≈.3937 inches). Conversion to centimeters is not new matter. Hinge can be, but is not limited to being substantially 3″ up, 3.5″ up, 2.5″ up, or 2″ up from file folder fold. Hinge can be, but is not limited to being substantially ¾″ tall, 1″ tall, or ½″ tall. Hinge portion horizontal widths can be, but are not limited to each being substantially ½″,¾″ or 1″. In example with a stapled hinge, tabs to make the hinge portions may each be 1 ⅛″ wide, where the staple is ⅛″ from the hinge portion's distal edges and 1″ from the hinge portion's proximal edges. Prior art scoring lines at/near the bottom edge of the folder can be, but is not limited to being, centered between folder front & back panels, so side hinge does not skew when folder expands.
Prior art tabs (extensions of and above a folder panel top edge) and cut-outs may be part of an embodiment. In Drawings, front and back panels are drawn similarly, but one could have a top tab and one could have a top cut-out (like in
The side hinge can be, but is not limited to being, equal-portion extensions from both front and back folder segments. The hinge can be an attached piece, like that shown in FIGS. 11 or 15. The bottom edge of folder panels can be a smaller dimension than folder side edges, like in
5. Materials
Materials that may be used to form panels and side hinge include, but are not limited to, those known in the art, including semi-rigid to flexible sheet materials like paper card stock, plastic sheeting, fiberboard, or corrugated cardboard. Folder stock can be, but is not limited to being, 9.5 to 25 pressboard stock, 14 gauge polyethylene. An attachment means, including a frontal and rear attachment means, may also be glue. The area of glued surface is small (like ¾″× 1/16″). Therefore it would be of advantage if such glue penetrated through the entire thickness of sheet material of both the folder and hinge parts, substantially attaching parts like a staple, versus surface attachment. If a folder were made of plastic, a prior art type heat seal may be an attachment means. So, attachment means can be, but are not limited to being, adhesive taping (such as strapping tape, cloth cold adhesive or heat-on tape, or Tyvek® tape), a staple, staples, glue, or heat seal.
12. Operation of the Invention and Unobviousness
My side-hinge folder may be most unobvious because the hinge does not always function as a perfect hinge or a prior art pleated side. Unlike a rigid hinge, when spreading the folder open, stress can be on the upper—most portion of the hinge. In use my hinge functions differently than prior art's customary pleats on both folder sides. That is, to put-in/take-out papers the prior art folder's pleated sides are needed to open equally top-to-bottom, like a pleated window blind. When my folders sit in a file drawer they behave as such. But most people tend to open only the top portion of a folder to insert papers, making a folder V shaped. Prior art pleats are tall, not-so-wide, and extend to the bottom of the pocket. So, opening a pleated-sides folder only at the top (V shape) pinches papers inside at the bottom, sometimes the sides near the bottom, stopping papers from getting all the way in. Prior art misses this problem. Because my main embodiments have a short hinge that is a distance from the folder's bottom edge, and generally avoids a W bottom, no pinching occurs. Unlike prior art, my single-side hinge has advantages by opening more V-shaped. That is, my folder opens V-shaped at and above the hinge and leaves a loose pocket bottom below it. My hinge, opening like a V above the hinge, lets a person view papers inside the folder and hold the folder up and review papers like a book (advantages #3, #4, & #13). My side hinge takes advantage of the natural V action of the panels' bottom hinge, like a standard one-fold folder.
With my taped hinge embodiments, versus my stapled hinge embodiments, the hinge may bulge laterally/outward from the folder panels, like in a not-so-full file. This bulging occurs more easily because the hinge is short and a distance from the folder's bottom edge. Unlike with prior art pleats, the pinching action of the bottom part of the pleated sides is not there to keep the hinge inside the folder (remember the V & W). Such a taped hinge may require but a touch to push the hinge in before inserting folder into a file drawer. Of course, my stapled hinges do not pop outside of the folder.
If folds, on/near the folder's bottom, are not bent equally between folder front and back my hinge may slightly skew. Perhaps those skilled in this art assumed this uneven stress was unworkable on a flat one-fold style folder. However, such stresses do not reduce the hinge's effectiveness and have negligible durability issues. Perhaps those in the art thought the folders bottom edge would need to be pleated, making them hard to stack as single folders.
Prior art folders (those more complex than the standard one-fold folder) are often over-engineered: most are complex to be sure papers stay inside a folder. Prior art misses that folders are most needed to have easy access to put in/take out papers (and secondly be multi-purpose). That is, it may be an unrecognized unsolved need that folders are most needed for sorting and reviewing (not just storing). My folder produces utilities unmatched in any other prior art folder, alone or in combination. As my folders are very multi-purpose and inexpensive to make, the fact that no one has implemented something even similar is evidence of unobviousness.
13. Conclusion
My folders have so many advantages: Papers slide in one way, so less likely any will be upside down. Papers line up evenly/same length in folder. Papers are easy viewed while in fairly-open folder/all data visible. Since papers can be viewed while in folder, papers stay in order. My folder expands up to 2″ wide. They are inexpensive to make and easy to produce. My folders can be placed in a backward-tilted tray making sorting papers super-extra-easy. On a backward-tilted tray, papers don't slip out either side. My folders, when full, pull from file drawers with contents intact (even if only one panel is grabbed). My folders fit anywhere standard file folders fit. The expanding side hinge can be clipped off if ever necessary. The side hinge can be hinged outward and be viewed as a side tab, especially if folders have few papers in them. Face the side hinge down, and papers can be looked at as if one were reading a book (without the papers falling out). My folders are aesthetically pleasing. The low position of the hinge on my folder keeps even envelopes from slipping out the folder's hinge side.
My folder is constructed to simply and effectively improve the order, direction, and straightness of papers in a folder. Papers actually go in easier, stay more organized, are easier to sort, and are easier to review than even the standard one-fold folders. My folder leaves all papers viewable and displayed with little opportunity for them to fall out. My folder shows: less is more, or having only one side expansion hinge (on a 2-sided folder) produces a better, unexpected result than more confining 3-sided expansion folders.
